This is a model used for mounting a fan to a ptc heater. There is also space to mount a wire connector and a thermal fuse.
- For easier access to screw holes (3mm diameter), mount the bracket to target surface before doing anything else using the 3 screw holes on the bottom
- Mount the heating element using 2 4x30mm bolts and nuts
- Mount the fan using 4 4x20mm bolts and nuts
- The box in the top right is used for the wire connections and thermal fuse
Parts list:
PTC Heater: https://www.aliexpress.com/item/1005009295466928.html (I used 24V 100W)
Fan: https://www.aliexpress.com/item/1005006306536871.html (I used 80x80x10mm 24V)
Thermal fuse: https://www.aliexpress.com/item/1005005464471286.html (I used 10A 100C)
2x 4x30mm bolt
4x 4x20mm bolt (if you chose 10mm thick fan)
6x 4mm nut
For connecting the wires and fuse I used a screw terminal block I had lying around. I used a simple cable tie to secure the terminal to the bracket.
The model is designed to be printed without supports, I recommend using a filament with higher temperature resistance (but of course the choice depends on the usecase, I used Bambu transparent PETG)
